, Description:FIELD OF THE INVENTION
The present invention relates to a synergistic storage stable hair wash/ treatment composition and more specifically, to a synergistic storage stable herbal 2-in-1 cleansing & conditioning hair wash/ treatment composition. Advantageously, the said synergistic 2-in-1 cleansing & conditioning hair wash/ treatment composition of the advancement is directed to a synergistic herbal hair wash/treatment composition with surprising and significantly special storage stability on one hand and on the other hand in delivering superior hair wash and conditioning benefits through desired foaming, cleaning and conditioning (hair smoothness) involving a 2-in-1 formulation which could effectively clean like a shampoo and also condition like a conditioner in a single step.

BACKGROUND ART
Cleansing/Shampoo compositions comprising combinations of surfactants and conditioning agents are well known. These compositions typically comprise mixture of surfactants in combination with a conditioning agent such as silicone or silicone emulsions, hydrocarbon oil, fatty esters, cationic conditioning polymers or combinations thereof.
Although cleansing/shampoo compositions cleans the hair by removing excess soil and sebum, cleansing/shampooing can leave the hair in a wet, tangled, and generally unmanageable state. Once the hair dries, it is often left in a dry, rough, lusterless, or frizzy condition due to removal of the hair's natural oils and other natural conditioning and moisturizing components. The hair can further be left with increased levels of static upon drying, which can interfere with combing and result in a condition commonly referred to as "fly-away hair", or contribute to an undesirable phenomena of "split ends", particularly for long hair. A variety of approaches have been developed to condition the hair. These approaches range from post-shampoo application of hair conditioners such as rinse-off product or leave-on products.
A common method of providing conditioning benefit to the hair through rinse-off conditioners is with the use of hair conditioning agents such as cationic surfactants and polymers, high melting point fatty compounds such as fatty alcohols, low melting point oils, silicone compounds, and mixtures thereof. Most of these conditioning agents are known to provide various conditioning benefits such as moisturized feel, softness, and static control to the hair. The conditioning benefits are basically delivered by the fatty alcohols and the cationic surfactants.
Hair conditioning composition such as rinse-off conditioner comprising the conditioning agents described above can provide conditioning benefits such as softness and moisturized feel on dry hair. However it involves two step applications of a cleansing/ shampoo composition first followed by a hair conditioning composition. Hence dual application of a cleansing/shampoo composition and a conditioning composition involves more application steps and more time.
Use of fatty alcohol in cleansing/shampoo compositions is known in the art. Fatty alcohol is known to deliver conditioning benefits in shampoo/ cleansing compositions such as good sensorial while application, ease of combing, moisturisation and smoothness. Typically these cleansing/shampoo compositions contain surfactant at a min 5% level. In shampoo composition, fatty alcohol tend to suppress the foam above 0.2% and tend to become unstable at above 4% level. Because of this, fatty alcohols are not used in commercial shampoo composition above 4% level. However, at less than 4% fatty alcohol concentration the conditioning benefit is not so desirable, like a conditioner. Thus it is a challenge to stabilize fatty alcohol above 4% in shampoo compositions.
Also there is a trend these days towards use of herbal products for all applications and more so for personal care products such as shampoos and conditioners. However suitable technology for incorporating effective amounts of herbs in compositions that provide simultaneously both cleansing and conditioning properties are not available. Further incorporation of high level of fatty alcohol also affects the foam volume and related characteristics as well as enhances the risk of phase separation. Also, as is widely recognized, herbal material in an aqueous medium tends to deteriorate over time.
Thus there is a need for herbal cleansing and conditioning compositions that are efficacious on both parameters, foams to accepted levels and at the same time stable from deterioration for long term storage.
Indian Patent Application Number 2254/CHE/2011describes a process for preparing a paste of single herb powder (shikkakai) for hair wash that requires high level of the herbal material (15-55%) in a medium that contains 15-50% of a non-ionic surfactant, 0.5-3.00% of a thickening agent, 2-5% of a suspension agent, 1-4% of humectants and other ingredients such as aqueous extracts of Fenugreek, aqueous extracts of Hibiscus, aqueous extract of Amla, anti-oxidants, preservatives and chelating agents. Shikkakai is a known herbal material containing saponins that has been used traditionally to cleanse hair. The patent application describes a process to make the herb available in convenient ready-to-use format but does not traverse the requirement of herbal cleansing and conditioning compositions that are efficacious on both parameters, foams to accepted levels and at the same time stable from deterioration for long term storage. The patent application does not indicate efficacy of the paste in cleansing requirements, and/or in desired foam generation and /or of its conditioning capability as well as its stability upon long term storage.
Indian Patent Application Number 547/MAS/2000 (Patent Number 201053) also describes a process for preparing a paste of single herb (shikkakai 26.2%) for hair wash that uses 3.2% of a fatty alcohol (cetostearyl alcohol) and 3.8% of sodium lauryl sulphate. The patent describes a process for making the herb shikkakai, a known source of saponins (natural surfactant) that has been traditionally used for cleansing hair, available in a convenient physical form without claiming / indicating any improvement in the performance of the paste over the herb or stability of the herb in the paste form. However, the patent disclosure does not in anyway address or demonstrate the requirement of herbal cleansing and conditioning compositions that are efficacious on both parameters, foams to accepted levels and at the same time stable from deterioration for long term storage.
Patent application WO 2014044660 describes a cosmetic assembly comprising at least two cosmetic compositions that are different from each other, a first aquatic composition comprising a cationic polymer and/or an amphoteric polymer; and a second aquatic composition comprising an anionic surfactant and a solid fatty alcohol. The said cosmetic composition especially for conditioning the hair, comprising a long-chain anionic surfactant, a solid fatty alcohol, an amphoteric or a cationic polymer, a nonionic surfactant and a water-soluble salt. Both the cosmetic assembly and cosmetic compositions are meant to condition the hair, but not to simultaneously clean and condition the hair. Basically this cosmetic assembly which comprise at least two different cosmetic compositions intended to deliver superior conditioning, especially the second aqueous composition that contains anionic surfactant and a solid fatty alcohol also intended to deliver conditioning, which implies that the anionic surfactant is less and the fatty alcohol is more; which is also evident from exemplary illustrations and scope of the advancement reflected from the statement of claims. Moreover, this patent does not incorporate herbal material among its ingredients and is significantly complex in its composition.
EP 0 555 690 A1 discloses a conditioning shampoo composition containing an anionic surfactant, a combination of long-chain fatty alcohol, and a long chain fatty acid, and a non-volatile silicone material with extended product stability, intended to deliver excellent cleansing, foaming properties and overall conditioning to human hair. This composition contains a mixture of fatty alcohol and fatty acid. The fatty alcohol having about 20 to about 40 carbons in the long chain and the fatty acid is having about 18 to about 36 carbons in the long chain. However, this patent does not incorporate herbal material among its ingredients and is also significantly complex in its composition as it includes multiple actives such as long chain fatty acids.
EP 0 865 272 B1 relates to compositions that provides both cleansing and conditioning benefit to the hair and comprise of a detersive anionic surfactant (other than anionic amino acid derived surfactants); a stabilizing surfactant selected from the group consisting of anionic amino acid derived, amphoteric, cationic surfactants or mixtures thereof; a fatty compound selected from the group consisting of fatty alcohols and its derivatives, fatty acids and its derivatives and mixtures thereof; a hair conditioning agent selected from silicones, hydrocarbon conditioning agents and cationic conditioning polymers and mixtures thereof; and water. This EP patent also does not incorporate any herbal material among its ingredients and incorporates expensive amino acid derived surfactants along with fatty materials as well as other conditioning ingredients such as silicones .
US 8361448 describes a shampoo composition that comprises one or more detersive surfactants, a dispersed gel network phase containing fatty alcohols and also water. The advancement under US 8361448 is directed to a process for the preparation of the gel network phase and does not address the issue of incorporating herbal solids/powder in the challenging requirement of formulation having cleansing attributes, good foam height as well as conditioning benefits.
It would thus be well apparent from the above stated that there has been inherent challenges in incorporating herbal solids/powder in formulation having cleansing attributes, good foam height as well as conditioning benefits. Moreover, it is a well known and appreciated challenge in the art that cosmetic composition such as hair wash/treatment compositions or skin treatment compositions containing high herbal solids/powder are usually unstable with respect to color, appearance (phase separation), odor and consistency in shelf life.
Hence there exists a need in the art to explore such compositions involving herbal powder which would not be unstable with respect to color, appearance (phase separation), odor and consistency in shelf life and yet provide for desired cleansing, good level of foam and conditioning superior to a 2-in-1 conditioning shampoo or as good as a rinse-off conditioner- all in a single step.
OBJECTS OF THE INVENTION:
It is thus the primary object of the present invention to provide a synergistic cleansing & conditioning hair wash/treatment composition incorporating herbal actives including as herbal powder that would provide a much desired storage stable herbal 2-in-1 cleansing & conditioning hair wash/treatment.
In another object , the present invention relates to a synergistic cleansing & conditioning hair wash/treatment composition incorporating herbal powders that would provide a storage stable 2-in-1 cleansing & conditioning hair wash/treatment involving >4% fatty alcohol so as to deliver superior conditioning / performance benefits while still delivering good foam characteristic.
In another object, the present invention provides a synergistic cleansing & conditioning hair wash/treatment composition incorporating herbal powder which on one hand has prolonged shelf life, and on the other hand imparts foaming, cleaning and superior conditioning and other do-good hair care benefits.
Yet another object of the present invention is to provide a synergistic cleansing & conditioning hair wash/treatment composition incorporating herbal powder for an extended period of at least two years with acceptable colour and smell upon storage at room temperature.
It is yet another object of the present invention to provide a synergistic cleansing & conditioning hair wash/treatment composition incorporating herbal powder and that would be useful as a rinse-off shampoo, cleansing conditioner, temporary leave-on pack, conditioning pack or an instant conditioning rinse-off that would deliver foaming, cleaning and superior conditioning and other do-good hair care benefits.

EXAMPLE 7 Comparative Evaluation of the synergistic herbal powder containing storage stable 2-in-1 Cleansing & conditioning hair wash/treatment composition of the present advancement vs. commercial products:
Table 7:
Parameters Commercial hair therapy shampoo vs. Inventive composition (Example 6) Commercial hair therapy shampoo + Conditioner vs. Inventive Composition
(Example 6) Commercial salon SPA treatment (shampoo, cream bath, serum)
(Example 6)

Hair smoothness( by salon half –head evaluation) 100% preference for Inventive composition 80% Preference for Inventive composition 60% Preference for Inventive composition
Large panel Consumer Study (Panel Size 180/ 6 centres) 94.5% Consumers rated Inventive composition superior to commercial hair therapy shampoo on overall preference 84% Consumers rated Inventive composition superior to Commercial hair therapy shampoo + Conditioner on overall preference 71% Consumers rated Inventive composition superior to commercial salon spa treatment on overall preference
The above data shows that inventive composition is preferred over a commercial shampoo and shampoo + conditioner in salon half head evaluation. In large panel consumer study it was rated superior over the commercial shampoo and shampoo plus conditioner. This also shows as a single product this is preferred over a dual combination of shampoo + conditioner and a multi combination spa treatment( shampoo, cream bath & serum).

Example 10: Process for manufacturing the synergistic storage stable 2-in-1 cleansing & conditioning hair wash/treatment paste
A Process for manufacturing the storage stable 2-in-1 cleansing & conditioning hair wash/treatment paste as described in above examples (sample 1 to 35) comprise the steps of:
(i) Taking fatty alcohol in a kettle, heating it to 70-80 Deg C and melting it completely
(ii) Taking water in the other kettle and adding surfactants and other water soluble ingredients heating to 80-85 Deg C
(iii) Adding hot fatty alcohol phase into the hot water phase and homogenize for 10-20 minutes and cooling the resultant mixture
(iv) Pre-dispersing the herbal powder in water and add the dispersion to the composition obtained in step (iii) and mixing it thoroughly
(v) Adding the preservative to the composition obtained in step (iv)
(vi) Optionally adding other hair benefitting ingredients mixing it thoroughly
It is thus possible by way of the present advancement to provide for a synergistic herbal solids containing storage stable 2-in-1 cleansing & conditioning hair wash/ treatment composition by way of the selective synergistic combination of herbal solids, at least one fatty alcohol and at least one surfactant. Advantageously, the synergistic composition of the present invention on one hand is shelf stable and on the other hand delivers superior conditioning performance (hair smoothness) and is also adapted to deliver foaming, cleaning and conditioning (hair smoothness)in single step and that can be used as an instant rinse-off or temporary leave-on to deliver the above said benefits.
